In Corda 3, getting Quasar ClassReader exceptions when running runNodes

When I run the runNodes task to start nodes in Corda 3, I get the following exception:

WARNING: An illegal reflective access operation has occurred

How can I fix this issue?

You will see this issue if you use the wrong version of the Oracle JDK. Corda requires the Oracle JDK 8 JVM, with a minimum supported version of 8u131.
